Definitions

  • the present invention relates generally to electrical connectors and power switches, and more particularly to a combination, one-piece integral electrical connector and rocker type power switch module which is particularly intended for use in connection with and mounting upon a printed circuit board (PCB).
  • PCB printed circuit board
  • Rocker type switches comprising for example, a rocker element operatively connected to a substantially U-shaped contactor having a hairpin configuration
  • Rocker type switches are of course well known in the art and are exemplified by means of the rocker switches disclosed within U.S. Pat. Nos. 5,293,018, 4,982,061, 4,272,662, 3,879,592, 3,749,872, and 3,670,121.
  • electrical connectors having a vertical and horizontal array of 90° angled terminals and adapted to be connected to and mounted upon a printed circuit board (PCB) are likewise well known in the art and are exemplified by means of U.S. Pat. Nos. 5,676,554, 5,639,250, 5,482,470, 5,366,381, 5,236,375, 5,173,161, and 3,493,916.
  • the electrical switch is usually mounted upon a suitable bracket and then operatively connected, by suitable electrical wiring, to the electrical connector which, in turn, is electrically connected to the printed circuits of the printed circuit board (PCB) as a result of the electrical connector being mounted upon the printed circuit board whereby end portions of the terminals of the electrical connector are electrically engaged with or connected to the printed circuits of the printed circuit board.
  • PCB printed circuit board
  • electrical power switches and electrical connectors operatively associated with, for example, printed circuit boards (PCBs), as separate or discrete entities, elements, or devices however, is simply not economical or cost-efficient from a manufacturing and/or assembly point of view for several reasons. Firstly, the electrical connectors and the power switches must be separately manufactured. Secondly, the electrical connectors and power switches must be separately inventoried and distributed to suppliers and end users, that is, manufacturers, for example, who will use such elements or devices in connection with the manufacture of various electrical systems or components. Thirdly, when such end user manufacturers incorporate such electrical connector and power switch elements within the manufactured systems or components, the connectors and switches must be separately mounted upon their respective support members and then electrically connected together. All of these assembly operations are necessarily labor-intensive and time-consuming.

  • opposite sides of the horizontally extending section 32 of switch housing 14 are respectively provided with resilient or flexible detent clamp members 66R,66L, having a substantially C-shaped configuration, within which the first horizontally extending portions 60R,60L of the wireform contact members 56R,56L are snap-fittingly engaged.
  • the second horizontally extending portion 64R of the wireform contact member 56R serves as a make/break contact member
  • the second horizontally extending portion 64L of the wireform contact member 56L serves as a common contact member.
  • the substantially U-shaped hairpin type contactor 48 is provided with a relatively long leg 68 and a relatively short leg 70, and a concave or recessed portion 72 is defined within the longer one 68 of the two leg portions 68,70 of the contactor 48.
